A system is described for the measurement of fast transient responses of leaf gas exchange to lightflecks. Any chamber adulterates a true signal unless in the steady-state; therefore, a procedure for estimating an 'effective chamber volume' is presented which is an essential parameter for correcting a measured transient signal. A common correction is critically commented on. With the system, responses of net photosynthesis to lightflecks as short as 1 s have been observed in leaves of seedlings of Fagus sylvatica L.
描述了一种用于测量叶片气体交换对光闪烁快速瞬态响应的系统。除非处于稳态，否则任何气室都会干扰真实信号；因此，提出了一种估计“有效气室体积”的方法，这是校正测量瞬态信号的一个基本参数。对一种常见的校正方法进行了批判性评论。利用该系统，观察到了来自欧洲山毛榉（Fagus sylvatica L.）幼苗叶片的净光合速率对 1 秒以下光闪烁的响应。
